I used the term "vanilla" because of its common usage in the C community. I
did not mean to imply that K&R C is the most common version of C. Certainly
ANSI C is available for every current platform that I am aware of, and the
vast majority of the C code written in the last few years has been written
in ANSI C.

My apologies. This is the type of mistake that my spell checker will not
protect me from!

One of the reasons that C99 is not catching on as quickly as C89 / C90 is
that so much of the C market has transitioned to C++, where again full
declarations are required. So all of this is quickly becoming a moot point.
